, Referring.. to A the dra-Wings, andy to thenenibodinient of the invention Whichjisfselected for `eten)plilication, I thereis shown a a lubri- Caterv comprising a reservoir 4liaving'an inlet and an outlet 6, the latter to be connected'vvith the bearing to belubricated In the present example, the reservoir is formed asa part of a. casing l@conveniently ,stamped oridraivnfrom sheet metal, and presenting 'fatitsflower end avthreaded nipple Spisurrounding 'the outlet ,6, and which inayjbe screwed into an opening leadingvto thebearing. v

To vensure an ample supply of lubricant between the bearing,- surfaces, and to. carry away foreign substances and Worn metal, as Well as old, vitiatedV lubricant, provision is made forinitial loodingof the bearing, folloived'by a 'relatively slow'feeding of lubrieant thereto. To this end, inthe present embodiment, the outlet is normally closed byian outlet valvecoinpiising a pervious disk 9,A

1 `i'eiveiii presented an inclined wall 11 havf` ing a'frusto-conical form, which guides `the valve toward its normal 'central position uas` it is closed.

- f The valve isno'iinally seated, and prevents rapid escape of the oil therethrough, but When'jliftedV *toA some such position as that illustrated in Fig.` 2, permits -a flooding of the bearing @n the other hand, when the,

valve isfclosed, a 'slowv ,feeding of oil to A'the bearing i'spermitted, by reason of the-fact thatth'e disl is pervious.

' Tlerein,

the yop(eratioiis.fofl the cover` and valve are yco-ordinated,pand. suitable jmeans jare provided yieldinglyl to resist opening of the cover vand* yalve,and to :restore themfto their closed positions aftery being opened. Toy Athose nds,l 1in the present example,l the byza stem 15, which is secured to the cover,

Vagainst an abutment .i presented by an out-y wardly directed tlangeQO,carried bylthe loWerYend ofthe ste'nn. The valve is `convenient-ly secured to 'the stem by `a screw 21 extending tliroiigli--=the va-lve, and threaded into the stein, In the presentexainplefa Washer 2 2, provided with` perforations 23,y presents fa stoplto limit descent of the valve' 4'cover andY valve :areconneoted to each other 1 An enlarged tapered, so

to theirnorinal posiunder the iniluence ofthe spring which might otherwise compress-'the felt valve suifi-v j ciently to closetlie air vent'll. VAls shown in 3F l. the valve is somewhat compressedfbef fore the ,stop seats. Seepage of oil takes place through the felt valve, andthe oil escapes through the perforations.,

Tooperate'the lubricator, the Vcover -is first f lifted from the position'sliown in Figylfto'f some such positionas vthat representedf in Fig.. 2 and lubricant is supplied to thek reser-AV voir. It follows that atrst, vthe lubricant Will run. freelyfthroughthe voutlet tothe bearing, thus flooding-the latter. Vhen the;

Vloof Y vbearing has taken up all the oil it can hold,

Vallowed to close underftlie influence of the spring. `The Workingpart which is thus lubricated can bestarted With Vthe assuranceV of an'ainplev supply ofV oil'. Subsequently,

. duringthe operation, a slow feeding of oil takes place by Way of the normal feeding de-V y vice, herei n by' seepage through the felt ment Vof'said cover to be accompanied by4 y valve, the density and proportionsv 'of which are such as to permit the proper krate of feedingtosuit the'particular circumstances.'
